Is Fan Control Possible via PS3 CFW?

Games like RE5, Castlevania LoS, MGS4, and some others started having green/red flashes and polygon tearing.

At first, I thought maybe the thermal compound was wearing out, as it's been a couple years. So I opened it up, replaced Sony's thermal grease (which was dried up) with Arctic Silver 5, then reassembled. The issue still occured.

Upon (a lot of) further testing, I found the issue was simply overheating. However, the PS3's fan would never kick up to a reasonable level to move out all the excess heat. It felt like an oven on the back side of my PS3. So I did a potentiometer mod and can now manually control the fan speed.

Turning the fan up only one level above what the PS3 would auto, has fixed my issues. The fan moves out plenty of heat now, and all my graphical issues are gone even after hours of play.

So long story short, would CFW be able to have an option added to control the fan speed? Or is it all hardware based? Cause my PS3's thermal sensor simply isn't doing the job properly.
